And what if your “old” diesel Defender rolled out of the shop with a factory big V8 under the hood and a chassis that’s been completely redesigned? For owners of the latest Land Rover analogs, the idea had until now looked like a fantasy reserved for independent tuners. JLR Classic has just decided that dream can wear an official badge, backed by a maintenance log to prove it. That’s enough to seriously tempt you to wheel your sleeping Defender out from the back of the garage.
On September 23, 2026, the Land Rover Classic division unveiled a new upgrade program for the Defender L316 models powered by the Puma diesel, built from 2007 to 2016. At the top of this offering sits the Defender Works V8 Conversion, an official retrofit that installs a 5.0-liter naturally aspirated V8 producing 405 hp, paired with an 8-speed automatic ZF transmission. The package includes substantial work on suspension, brakes, wheels, and certain detailing. A purposeful move by Land Rover to make these Defender 90 and Defender 110 more desirable than ever, without replacing them with a new model.
A Factory V8 Conversion for Defender 90 and 110 L316
The program covers all Land Rover Defender L316 90 and 110 models with Puma engines built between 2007 and 2016, but not every unit can receive the V8. The chassis and braking kits remain available across the entire period, while the Defender Works V8 Conversion itself is limited to 2012–2016 models. In other words, a first‑owner utility 90 could receive upgraded suspension and brakes, but only the newer Defenders would get the factory V8. The rest of the lineup isn’t forgotten, with the option to benefit from improved handling and braking nonetheless.
Under the skin, Land Rover pairs Bilstein dampers with Eibach springs. The aim is to improve ride comfort and body control. The Alcon braking setup uses four-piston calipers and 335 mm discs at the front. In back, the discs reach 300 mm—a meaningful upgrade from the original Puma brakes. Buyers can opt for 16‑inch steel wheels or 18‑inch alloys. The cabin also gains a redesigned gear tunnel and distinctive Works V8 badging. Dominic Elms, head of JLR Classic, sums up the spirit of the program, describing it as built for a Defender that can be a beloved family companion, a reliable work tool, or a valuable collectible.
Defender Works V8 Conversion: 405 hp and a Fully Mapped Transformation
At the heart of the conversion sits a 5.0-liter naturally aspirated V8 developing 405 hp. It delivers 380 lb-ft of torque (about 515 Nm). The power is routed to all four wheels via an 8‑speed ZF automatic transmission. This choice of a naturally aspirated V8 contrasts with the turbocharged V8 found in today’s Defenders. It better suits the more analog character of the L316 generation. For the complete conversion, Land Rover guides owners to its Classic Works facilities in the United Kingdom and Germany. On site, specialized technicians handle the mechanical replacement. The brand leans on the experience gained from its meticulous restorations. This is far from a simple online kit.
This service isn’t available everywhere or for every Defender. Land Rover notes that final eligibility, specification, price, and timelines depend on the vehicle’s condition and equipment. The market in which it operates also matters, with approval following an assessment by a Classic specialist or a local dealer. Owners can also order suspension, braking, or wheel components through the Land Rover Classic Parts site. Installation can take place at home or at a dealership, but the V8 conversion remains restricted to Classic Works workshops. The American outlet Motor1 points out that a swap performed and documented by the official network keeps provenance in the vehicle’s file, which reassures insurers and buyers. A home installation, even one based on original parts, will be scrutinized more closely at resale. Some collectors committed to originality will prefer to keep their Defender as it is. Others will see this factory V8 conversion as a way to enjoy their 4×4 daily while rendering it almost irresistible.
